Common pneumatic components: air compressor, aftercooler, air receiver, dryer, water separation filter, oil mist collector, muffler, cylinder, pressure control valve (pressure reducing valve, sequence valve and safety valve), flow control valve (throttle valve, one-way throttle valve, exhaust throttle valve), direction control valve (one-way control valve, reversing control valve), buffer, magnetic switch, universal joint (floating joint) Fisheye joint
Connector: quick connector/quick connector (internal thread or external thread), type of connector thread (metric thread M, taper thread (R), G): M5, R1/8 (1 split thread (outer diameter of thread about 9.7mm)), R1/4 (2 split threads (outer diameter of thread about 12.7mm)), R3/8 (3 split threads (outer diameter of thread about 16mm)), R1/2 (4 split threads (outer diameter of thread about 20mm)), etc.
Cylinder: pencil cylinder, pull rod cylinder, guide cylinder, linear sliding table cylinder, rodless cylinder, rotary clamping cylinder, rotary cylinder.
Speed control valve shall be installed at both ends of the cylinder
During cylinder commissioning, its throttle valve shall be gradually opened from the fully closed state, and the driving speed of the cylinder shall be slowly adjusted to the required speed from the low speed.
The throttle valve is generally installed in two ways: exhaust throttle and recent throttle. The exhaust throttling method is mostly used in pneumatic systems, because the back pressure generated by the cylinder during operation through exhaust throttling makes the travel speed of the cylinder or its speed adjustment more stable, and it can avoid the piston rod from suddenly advancing rapidly and hitting the cylinder head when starting.
When the cylinder with buffer is commissioned, the buffer valve installed on the cylinder head shall be readjusted from small to large to the cylinder without rebound according to the size of load and speed. Note that the buffer shall not be tightly adjusted during the adjustment process, otherwise the buffer will be poor or the piston will damage the seals under rapid conditions.
Calculation formula of cylinder output force:
F: Cylinder output force (kgf)
A: Section area (cm ^ 2)
P: Working pressure (kgf/cm ^ 2)
f: Friction resistance (kgf)
1kgf/cm ^ 2=1.01972bar (bar)=10 ^ 5Pa=0.1MPa
The theoretical output force of the cylinder can be found in the supplier‘s selection samples.
Check the allowable turning torque and load torque of the cylinder (side load, plane load, transverse load)
